The second series of £1 coin designs used heraldic emblems to represent
the United Kingdom and its four constituent countries. This coin features
the Broighter collar over a Celtic Cross to represent Northern Ireland.
The Broighter collar was discovered in 1896 amongst a hoard of gold Iron
Age artefacts near Lough Foyle in Northern Ireland, and is said to be the
finest example of Irish La Tène goldworking in Europe.
